从字面上看,我需要做的就是：

SELECT price,sqft,zipcode FROM homes WHERE home_id = X

当我使用PHP PDO时,我已经阅读了推荐的连接MysqL数据库的方法,只需创建连接就需要610毫秒.

我的代码如下：

try {
    $conn_str = DB . ':host=' . DB_HOST . ';dbname=' . DB_NAME;
    $dbh = new PDO($conn_str,DB_USERNAME,DB_PASSWORD);
    $params = array();    
    $sql = 'SELECT price,zipcode FROM homes WHERE home_id = :home_id';
    $params[':home_id'] = X;
    $stmt = $dbh->prepare($sql);    
    $stmt->execute($params);
    $result_set = $stmt->fetchAll(PDO::FETCH_ASSOC);
    // json output  
    ob_start("ob_gzhandler");
    header('Content-type: text/javascript; charset=utf-8');
    print "{'homes' : ";
    print json_encode( $result_set );
    print '}';
    ob_end_flush();
    $dbh = null;
} catch (PDOException $e) {
    die('Unable to connect');
}

问题：连接到MysqL数据库以执行上述查询的最快方法是什么？
